Three finalists for 2012’s African Player of the Year were announced this week, though one candidate’s case makes him the clear favorite for the award. While Didier Drogba inspired in leading Chelsea to Champions League glory and Alex Song had his best year as a pro for Arsenal (mostly), neither player’s influence matched Yaya Touré’s. Though Robin van Persie’s goal totals won him last season’s major individual Premier League honors, Touré was the best player in the league, a dominating presence in the middle of the park that help capture Manchester City’s first Premier League title.

It’s no surprise Michael Cox, writing for the Guardian, picks out Touré when discussing keys to Sunday’s Manchester Derby. Against Manchester United, the Ivorian can be particularly influential against a team whose main weakness lie in the middle of the park.

Cox discusses Alex Ferguson’s options matching up with Touré in deep midfield, but it’s when Touré comes forward that Manchester City’s most effective. That Touré can start deep and still have a determining factor in the attacking phase (or, pushed forward later in matches) is part of what makes him an elite player. It’s also why relying on a forward to mark him (as, Cox illustrates, United has done in the past) is difficult to pull off. Touré can win most of those individual battles, and when he doesn’t, his movement forward pulls one of your attackers too far upfield.

Defensively, it’s better to concede Touré’s influence higher up the pitch and use a midfielder to pick up him as he ventures forward (something that almost requires playing three in the middle versus City). This is where Manchester United may miss a player like Anderson. The Brazilian midfielder has the strength and athleticism to compete with Touré, but sidelined with a hamstring injury, Anderson will miss tomorrow’s match. Ferguson’s other midfield options — Michael Carrick, Darren Fletcher, Paul Scholes, and Tom Cleverley — all beg a forward, Wayne Rooney, to come back into the picture.

Depending on how United set up, they may be able to dedicate Rooney to the role without undo damage to their attack. Ferguson has used a midfield diamond at various points throughout the season. If he plays Rooney at the top of that diamond, United can afford to have Rooney follow Touré deep into the defensive zone knowing the speed of Ashley Young and/or Antonio Valencia can bring van Persie and Javier Hernández back into the game.

Valencia, however, presents another option, one Ferguson’s highly unlikely to use. For Ecuador, the nominal right winger has player through the middle. In England, he’s ill-equipped to do so from an attacking perspective, but Touré’s presence (and Manchester City’s dependence on it) might justify giving Valencia the role Park Ji-Sung tried to perform last October. With his speed and strength, could Valencia be the man to help mitigate Touré?

We’ll likely never know. At least, not tomorrow. The most likely scenario sees Ferguson trust Rooney to stymy Touré, though as Cox points out, there are drawbacks to that plan, too.
